The data collected in the scientific studies included in the report began in March 2011 shortly after the nuclear disaster at Fukushima and continued for periods spanning months and years depending on the tests being done.
Due to the mass destruction of the area, the first few days’ data were not able to collect (not only the destruction, but the rescue was the first priority). Therefore, the scientific committee used models to simulate and analyse the data (might not be accurate on the early stage). After the rescue, many countries have provided data to assist the works. For the long‐live radioactive substances, the data was able to collect with the ground soils. Furthermore, prediction can be made with the pass experiences and the basic models.
The report collect the data after the Haiti's earthquake and epidemic, most reference data is between the 2011 to 2013. It is found many people in Haiti is still live in tents or under tarpaulins. The problem of emergency or reconsttuctions is come out.
The data for this report was obtained over a period from the earthquake in 2010 to 2012.
Data was collected since the beginning of the ebola outbreak in 2014 till sometime in 2015 before the article was published.
The data for this report were collected through over 70 interviews with people displaced from their homes and over 50 interviews with teachers, HCPs, activists, academics, lawyers, and government officials. In July and August 2004, with a follow-up visit to Bogot in September 2005.
The data for the rport was collected for the end of 2005 to the beginning of 2006.
Data for this report was collected from other sources and forms of documentation as early as the day of the event. Information and details such as population sizes, weather conditions that day, human population distribution and more were all information collected from that day of the event. Other forms of data collected, ranging over the time of the event occurring to the publication time, include factors such as the quality of the air, water, animals and living conditions surrounding the plant. Human radiation levels and infection were also gathered, radiation levels of crops and much, much more were all statistics and data collected over roughly twenty year timespan that this report covers. This is actually one of the main driving points of the report, listed in the title "twenty years of experience." It compiles 20 years of research and findings into one large report.
The report data covers from April 26th 1986 (the date of the disaster) to 2006 (the year the report was published).
